    rsync: rewrite -s option to -Wl,--strip-debug in LDFLAGS
    
    LDFLAGS containing "-s" calls gcc and/or ld with "-s" which means
    --strip-all with current (2.36) binutils and perhaps earlier versions
    this causes relocation entries in the .rela.plt section of type
    R_X86_64_IRELATIV to be replaced with 0-entries having type
    R_X86_64_NONE (value 0). This breaks the STT_GNU_IFUNC mechanism used by
    certain shared libraries breaking the rsync binary.
    
    Interestingly "strip -s" on the same binary which also is supposed to
    "strip all" does not show this behavior so it is somehow different from
    the behavior of ld. Perhaps it is a bug in binutils, though I was not
    able to find
